Definition#

Lift is the aerodynamic force acting perpendicular to the relative wind, generated primarily by the wings due to pressure differences between the upper and lower surfaces. In steady level flight, lift equals weight.

Why It Matters Operationally#

Lift must exceed weight for flight. Pilots control lift through angle of attack and configuration (flaps, slats). Understanding lift generation is fundamental to all phases of flight.
